The title says it all: I was passing by, saw this group and thought immediately of Martin Parr - as I raised the camera to my eye, the man in front made eye-contact with me and I pressed the shutter button and got Henri Cartier-Bresson's decisive moment for a two-fer!
I see by googling Martin Parr that this is the sort of photo he likes to take! It looks entirely natural here - everyone must have been on a long walk!
Thanks for introducing me to Martin Parr's work. :) Clearly, this is faithful to the theme. Personally, I am enjoying the chap at the back right, with his hair screwed up to a sharp point. Don't mess with him. ;) Nicely shot.
